A. A. BAKER SURFACE DRAIN Feb. 24, 1953 Filed June 17, 1950 Patented F eb. 24, 1953 SURFACE DRAIN Albert A. Baker, Erie, Pa., assignor to J. A. Zurn Manufacturing Company, Erie, Pa., a corporation of Pennsylvania Application June 17, 1950, Serial No. 168,689

6 Claims.

This invention relates generally to surface drains and more particularly to floor drains in which the level of a strainer member thereon is adjustable in a substantially horizontal plane and vertically througl'i successive parallel planes to conform to the level of a floor in which the floor drain is installed.

The tops of present floor drains are adjusted to the level of the floor after which cement is introduced around the periphery of the strainer or surface member of the drain. There is a certain amount of shrinkage of the cement when it hardens and seasons and this leaves the tops of present floor drains out of level with the floor. To remove the strainer members in present floor drains, it is necessary to chip the cement from around the upper strainer member thereof. The tops of present floor drains cannot be adjusted to the plane of an inclined floor. These present floor drains are formed of a number of different parts, making them costly in manufacture and assembly. The throats or mouths of these drains ar formed with obstructions which usually extend crosswise thereof, causing stoppages of the drain and making it impossible to pass test plugs thereinto for various required tests. Furthermore, it is extremely difficult to get into these prior floor drains to clean them.

It is, accordingly, an object of my invention to overcome the above and other defects in present floor drains and it is more particularly an object of my invention to provide a floor drain which is simple in construction, economical in cost, economical in manufacture, and efficient in operation.

Another object of my invention is to provide a floor drain with a minimum number of parts.

Another object of my invention is to provide a flcor drain with an increased area of unobstructed passageway for the passage of fluid from the strainer to minimize the impedance to the flow of water or other waste material through the drain.

Another object of my invention is to provide a floor drain which has no obstructions to cause stoppages and through which a test instrument may be projected.

Another object of my invention is to provide a floor drain in which the strainer member is adjustable in a substantially horizontal level and through vertically successive parallel planes and it is removable and replaceable at all times.

Another object of my invention is to provide a floor drain with a strainer member which is not cemented in th floor in which it is disposed.

Another object of my invention is to provide an adjustable leveling ring for disposal on a surface drain when the surface to be drained is inclined.

Other objects of my invention will become evident from the following detailed description, taken in conjunction with the accompanying drawings, in which 1 Fig. 1 is a plan view of my novel floor drain; and

Fig. 2 is a view taken on the line 2--2 of Fig. 1.

Referring now to the drawings, I show in Figs. 1 and 2 a cylindrical member I having a depending internally threaded flanged portion 2 for threadable connection with the upper threaded end 3 of a pipe 4 which may have any suitable connection on the lower end thereof for connection to a sewage or other drain pipe. The member I has a slightly conical circular shield flange 5 to drain seepage water through laterally extending apertures 6 into the throat of the member I. The member I has an inwardly extending annular flanged portion I internally threaded at 8 for threadably engaging the lower threaded cylindrical portion ll of a sleeve H2. The sleeve I2 has a conical shaped circular flange It with a flat annular seat It and with the outer side thereof flanged upwardly at I5. The sleeve I2 is initially adjusted to a predetermined vertical position with respect to a floor or roof surface and cement is disposed therearound to hold it firmly in a floor.

When the seating surface It is not in a plane with the floor or roof surface in which it is embedded as in an inclined floor or roof surface, I provide an annular leveling ring it having a flat annular upper seat I! and an upwardly extending, outwardly flanged portion It. The ring 16 seats on the seat It of the member I2 with th flanged portion is thereof seating on the flange I5 of the member I2. The conical shaped flange I3 on the member l2 has circumferentially spaced, inwardly extending bosses 3i! with threaded apertures 2I formed integral with the upper side thereof for threadably receiving screw bolts 20. A circular top surface or strainer member 22 having spaced slots 23 in the face thereof seats on the seating surface ll of the ring member I6. The strainer member 22 has circumferentially spaced countersunk apertures 24 for receiving the screw bolts 2c which threadably engage the threaded apertures 2? in the bosses 33 to secure the ring member It and the strainer member 22 onto the seat It of the sleeve E2. The inner side I9 of the leveling ring It is outside of the screw bolts 20 so that it may be rotated on the seat I4 to any desired position. It should be noted that the strainer member 22 will seat on the seat 14 of the member 12 when the leveling ring I6 is not required and it may be secured to the seat [4 by the screw bolts 20 engaging the threaded apertures 2| in the bosses 30. I provide a threaded aperture 25 in the leveling ring l6 for receiving a, screw bolt 26 which abuts the seat M of the sleeve l2 to raise one side of the leveling ring 16 upwardly from the seat 14 to adjust the horizontal level thereof.

In the disposal of my novel surface drain in a floor or roof, the member I and the adjustable sleeve [2 are embedded in whatever floor or roof material is used, such as cement, in a surface which is to be drained. The adjustable sleeve i2 is rotated until the top thereof is level with the proposed surface to be drained before the embedding thereof. If the top of the seat M on the sleeve I2 is level with the surface of the embedding material, the strainer member 22 is secured to the seat M.

In the event that the seat 14 is not in the same plan as the floor surface as in the case of an inclined floor or roof surface, the leveling ring [6 is disposed thereon as shown in Figs. 1 and 2. The screw bolt 25 is then threadably engaged with the threaded aperture 25 in the ring member I6 and it is abutted against the low side of the seat l4 and leveled with the floor surface.

The screw bolt 26 is rotated on its own axis and on the seat 14 of the member l2 until the ring member 16 is in the same plane as the floor surface. Additional adjustment may be obtained by rotating the sleeve l2. After the ring member [6 is level, the strainer member 22 is disposed thereon and the screw bolts 20 are threadably engaged with the threaded apertures 2i in the bossed portions 20 of the member 12. There are no obstructions to the flow of fluid through my novel drain and a maximum amount of Water may be carried away by it.

It will be evident from the foregoing description that I have provided a novel efficient adjustable fioor drain which has a minimum number of parts, which has novel adjustable detachable means for disposal on the upper side thereof for adjusting the top level of the strainer member, which is relatively economical in cost and easy to manufacture, and which is easy to assemble in a floor.

Various changes may be made in the specific embodiment of my invention without departing from th spirit thereof or from the scope of the appended claims.
